Ok, I'mma just put my main reason for not being too much on team Han here right now.
His past actions can cause some red flags especially when Param clearly wants a serious relationship. It would have been different if Param had heard the rumors from Han himself and cleared things up where Han had said he wants a serious relationship with Param but throughout a lot of this Han's feelings almost seem random and (FOR RIGHT NOW) we have no reason behind those feelings.
Not to mention that situation with the other guy and Param was a lot. Imagine thinking that you and another person may get into a relationship after the other person has expressed interest and then this situation happens. It's honestly a lot and not to mention the mental hoops Param had to go through with thinking that Han wasn't gay.
I'm not saying he is a no but I would like to get more of an explanation from Han as to why he likes Param, what relationship he wants, and just get to see more of his character.

This series is definitely well written. I found myself sympathetic to Alex only to remember who he was. I found myself rooting for certain cute parts in the relationship only to realize it wasn't a relationship at all, it was an arrangement. Clark although he could not comprehend his emotions was definitely in love with his ex. I also think that just like Alex Clark only needs one person caring about him in his life for him to feel satisfied which is why he told the investigator "I'm glad you're in love with me".
he actually said “i’m glad you’re not in love with me”
The Inspector should be glad he isn't in love with Clark too. Because Clark is definitely gonna have some major mental issues later down the road. That was some serious traumatizing moments.
